@David-TP Can I configure my 2 Deco M4 units to utilize different channels when employing wired backhaul, thus preventing interference? One serves as the main router, and the other acts as a satellite connected via an Ethernet cable.

  @David-TP Still u did'nt check my issue regarding ports not open for 5-7 minutes after i reboot my main deco and not getting internet until ports are not coming back

  @David-TP 

Tested various miscellaneous ways to make the client " connection preference " settings to stick, but no joy. 

Clients will randomly reset their preferences, although they stay connected to whatever deco was selected before they reset.

Btw where does the client " connection preference " settings get saved to exactly ? The mobile deco app ? Or on the deco itself ? 

Regards.

  @David-TP what about deco E4,will it support connection preference option? I have M4 v2 2 pack and 1 e4 mixed.after upgrading the deco m4 firmware to beta still there is no connection prefernce option.but if i dont use deco e4 then the connection preference option works.will there be any firmware released for deco e4?

  @David-TP 

I just updated all my 3 x M4r V2 to this firmware (from 1.6.2 Build 20240308 Rel. 55841), as I've had serious connection problems. It didn't do much difference, so I decided to factory reset my main Deco. I also isolated the rest of the network, so now it's only ROUTER - DECO with wire, no other devices on the LAN. And all other Decos are powered off.

1. Deco flashing blue, OK

2. New Wifi Deco_57CC visible

3. Deco app cannot find the Deco, even when Deco_57CC manually connected

I tried with PC and Deco_57CC gives me IP of 192.168.68.100 and Deco sits in 192.168.68.1. I can access the Webui, but it only says "Download TP-Link app....".

So is that new firmware preventing that Deco initial setup somehow?

  Replying to myself:

I managed to connect o my resetted Deco. I shut down Deco & mobile phone few times and lastly disable Mobile Data from phone. No idea which of these made the trick, but now it's back up and running.

For some reason, when I activated my IoT network with old name & psw for 30 clients or so (mostly ESP, Sonoff, Tuya), the whole network became unstable again. Traffic is quite low from any IoT device, 1-50kbs. Speedtest takes like 10 secs before anything happens and some PING packets get lost. It differs from time to time.

- What could cause this kind of issue?

  @ImtiazAli Mine is V1, so I guess I have to wait...tp link still hasn't confirmed about E4 V1.
